This Glow-worm interface board is suitable for use in CXI, HXI, C-CI, SXI, Xtramax, British Gas and SI boilers. The control centre of a boiler, the printed circuit board (PCB), or interface board, monitors and controls every process occurring throughout a system via switches, thermostats and sensors. It enforces safety measures too, shutting down boiler functions if internal readings indicate any fault such as high pressure or low water levels.
